ROSE—MEXIUAN AND CENTRAL AMERICAN PLANTS. 311 
cuneate at base; racemes usually shorter than the leaves, 3 to 4 em, long, becoming 
sometimes 6 cm. in fruit; calyx campanulate, 1 mm. long, brownish-pubescent, its 
teeth minute; banner of corolla 6 mm. long, densely covered with brownish hairs; 
wings and kee] glabrous, pinkish or light violet; pods whitish-pubescent, reflexed, 
2 to 2.5 em. long, slightly flattened. 
Only known from Monte Alban near Oaxaca City, but here found by several col- 
lectors. Specimens have been distributed as I. palmeri, but it is certainly quite 
distinct. 
Specimens examined : 
Oaxaca: Monte Alban, Rose and Hough, June, 1899 (no, 4583, type); Charles 
L. Smith, September 5, 1894 (no. 336); Lucius C. Smith, 1894 (no. 309); Con- 
zatti and Gonzales, July and August, 1900 (no. 1027). 
Named for my good friend Prof. C. Conzatti, who guided me to Monte Alban and 
who in many ways assisted me while in Oaxaca in 1899. 
Indigofera montana Rose, sp. nov. 
Herbaceous or perhaps shrubby at base, 60 to 120 cm. high; leaflets 21 to 31, oppo- 
site, oblong, 10 to 20 mm. long, obtuse or retuse, mucronate, more or less tapering at 
base, appressed-pubescent on both sides; racemes blackish-pubescent, elongated 
but shorter than the leaves; calyx broad, clothed with blackish appressed hairs, 
5-toothed, 1 mm. high; teeth small, acute, shorter than the calyx tube, not thick- 
ened, the two upper ones widely separated, the 3 lower approximate; banner 
blackish-pubescent without, 4 mm. long, folded and somewhat hooded at top, 
sessile; keel retuse at apex; ovary curved, 3 or 4-ovuled, covered with blackish 
hairs; pods probably curved, those seen immature, Perhaps nearest J. lindheimeri, 
but with different pubescence, calyx, leaflets, etc. It is probably also found at higher 
altitudes.
